An alert update conflict may
occur in Microsoft Operations Manager (MOM) 2005 when you use the MOM-to-MOM product connector to
connect a source management group and a destination management group. Additionally, when you try to use multiple management groups in a
multi-tiered configuration, updates that are made to alerts
in the destination management group may not be applied in the zone management
group. For example, the problem may occur if you modify the repeat count of an alert.
This problem occurs if the alert is updated separately in a source management group and in a destination management group in the same polling period. By default,
the source management group update takes precedence. The update in the
destination management group is dropped when a conflict occurs.
A
hotfix is available that lets a MOM 2005 administrator modify the MOM 2005 configuration so that the destination management group update takes
precedence when an alert update conflict occurs.
After you apply this hotfix and set a registry
key on all source Management Servers, the default behavior is reversed. When an alert update conflict occurs, a
change in the destination management group takes precedence over a change in the source
management group. However, changes in
the source management group are not applied in the destination management group
when a conflict occurs.
